Reseña del editor:

Use cases have become a very popular requirements-gathering technique, yet many developers struggle when faced with writing them. They grasp the basic concepts, but find that writing effective use cases turns out to be more difficult than they expected. One factor contributing to this difficulty is that the community lacks objective criteria for judging the quality of use cases. This new book articulates the qualities of effective use cases by applying the proven patterns concept of development to this requirements-gathering technique. The authors present a catalog of thirty-six patterns that help the reader become proficient at judging the quality of their (and other's) patterns. These patterns represent solutions to recurring problems that application developers have faced in writing use cases. Each pattern is presented with examples that help the reader understand the benefit of the pattern, and just as importantly, the consequences of ignoring its proper use.

Contraportada:

Use cases have become an integral part of modeling software requirements, but many software developers are discovering that writing effective use cases is more difficult than they had anticipated. An understanding of the basic principles of use cases is not enough. Software developers need a source of objective criteria by which to judge quality and effectiveness.

Patterns for Effective Use Cases provides this set of objective criteria. Written by experienced use case practitioners, this book fills a critical information gap by presenting a pattern language that contains over thirty patterns, providing simple, elegant, and proven solutions to the most common problems in use case development. These patterns distill and define the properties and characteristics of quality use cases. As such, they facilitate the development of original use cases and provide a diagnostic tool for evaluating existing ones.

The book opens with a review of use cases and pattern fundamentals, along with a discussion of the requirements-gathering team. These patterns address the use case development process, the internal structure of use cases, and the relationships among use cases within the system as a whole. Examples of patterns include:

• BreadthBeforeDepth
• VisibleBoundary
• EverUnfoldingStory
• IntentionRevealingName
• PreciseAndReadable
• LeveledSteps
• InterruptsAsExtensions
• RedistributeTheWealth

Each pattern discussion includes at least one example demonstrating its real-world application, highlighting both the benefits of using the pattern and the consequences of not doing so. In addition, the book presents guidelines for the effective use of UML with relevant patterns.

Anyone involved in use case writing or requirements gathering will find Patterns for Effective Use Casesan indispensable handbook and reference.
